Patent number: 7497632Abstract: A camera is covered with a camera housing. The camera and the camera housing form a shooting window portion of a double structure having a clearance. A blowing tunnel communicated with the clearance of the shooting window portion is arranged on each of both sides of the shooting window portion. A blower sends a wind to the shooting window portion through the blowing tunnel. Further, a heater for heating the air sent to the shooting window portion is arranged in the blowing tunnel. Thus, dew condensation preventing ability can be improved by such a construction.Type: GrantFiled: June 3, 2005Date of Patent: March 3, 2009Assignee: Panasonic CorporationInventors: Tetsurou Kajino, Jyouji Wada, Yoshihiro Fujiwara, Takayuki Shimaoka

Publication number: 20080292338Abstract: An image forming apparatus includes an image carrier, an image forming member, a transferer, a toner image detector, and a controller. The transferer transfers the toner image from the image carrier directly or indirectly onto a recording medium transported by a surface moving member. The toner image detector detects a test toner image formed in a test toner image detection area located at an end portion of the surface moving member. The controller checks a length of the recording medium in a main scanning direction during continuous image formation, and forms the test toner image either in a space between recording media when the length of the recording medium exceeds a length of the surface moving member minus a length of the test toner image detection area in the main scanning direction or otherwise in parallel to the toner image transferred onto the recording medium.Type: ApplicationFiled: May 22, 2008Publication date: November 27, 2008Inventor: Yoshihiro FUJIWARA

Publication number: 20080145102Abstract: A surface moving body includes an endless surface that is capable of making an endless movement. A surface-moving-body drive mechanism includes a driving source of a driving force for moving the surface moving body and a drive transmission mechanism for transmitting the driving force from the driving source to the surface moving body. At least a part of the surface-moving-body drive mechanism is arranged in a surface-moving-body occupying space surrounded by two surfaces defined by ends of the endless surface in a width direction orthogonal to a surface moving direction of the endless surface and the endless surface.Type: ApplicationFiled: December 12, 2007Publication date: June 19, 2008Inventors: Tsutomu Katoh, Mitsuru Takahashi, Nobuto Yokokawa, Kazuosa Kuma, Takeshi Fukao, Yoshihiro Fujiwara, Yoshiharu Kishi

Patent number: 7280792Abstract: A method for evaluating an electric resistance member of an image forming apparatus which can maintain good image quality, without the occurrence of transfer defects such as insufficient transfer, even in a long-term use. An intermediate transfer belt of the image forming apparatus, which is evaluated based on a fluctuation characteristic of the resistivity in a period of continuous voltage application, is used. The absolute value ??s of the amount of changes in the surface resistivity of the intermediate transfer belt within 2 seconds to 100 seconds from the beginning of voltage application is 0.3 [Log(?/)] or less, when the surface resistivity ?s is measured by applying a voltage of 500 V. The absolute value ??v of the amount of changes in the volume resistivity within 2 seconds to 100 seconds from the beginning of voltage application is 0.5 [Log(?·cm)] or less, when the volume resistivity ?v is measured by applying a voltage of 200 V.Type: GrantFiled: June 7, 2004Date of Patent: October 9, 2007Assignee: Ricoh Company, Ltd.Inventors: Yuuji Sawai, Yoshihiro Fujiwara, Shin Kayahara, Hiromi Ogiyama, Atsushi Takehara, Ken Yoshida, Shinji Kato

Patent number: 7101095Abstract: A housing of a rotation type camera apparatus has a standing installation surface for standing installation and a wall-mounting installation surface for wall-mounting installation. The housing is also provided with a dome type cover composing a shooting window facing in a slanting direction with respect to a horizontal direction in a standing-mounting position and in a wall-mounting position. A camera is provided so as to be able to shoot outside from the shooting window. A camera rotation device is accommodated in the dome and has a pan rotation axis based on the horizontal direction. The shooting window faces in an appropriate direction in both the standing-mounting position and the wall-mounting position. Since the pan rotation axis is set based on the horizontal direction, a viewer's eyes do not run up and down so much during the pan rotation.Type: GrantFiled: March 22, 2005Date of Patent: September 5, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsurou Kajino, Jouji Wada, Yoshihiro Fujiwara, Gil Palma Guerrero, Jr.
